OBJECTIVE: We describe a woman who presented with a psychiatric disorder post-partum and subsequently developed seizures and cognitive dysfunction prompting further investigation. A diagnosis of limbic encephalitis (LE) was made and antibodies to voltage-gated potassium channel complex (VGKC) detected. These antibodies are found in many non-paraneoplastic patients with LE. Although antibody-mediated conditions tend to present or relapse post-partum, VGKC-LE in the post-partum period has not been described. DESIGN: Case report. RESULTS: Clinical and imaging data were consistent with limbic encephalitis. High titres of anti-VGKC-complex antibodies confirmed the diagnosis of VGKC-LE. CONCLUSION: The similarities between the psychiatric symptomatology of VGKC-LE and post-partum psychiatric disorders raise the possibility that some instances of post-partum psychiatric conditions are manifestations of immune-mediated, non-paraneoplastic LE.
